clenched through the seam to be connected,

by the operation of a foot lever.

Another object is to provide a magazine for automatically feeding tacks through the one jaw member from the inside of shoes by the operation of a foot lever. Other objects will appear from the follow ing description and appended claims as well as from the accompanying drawing, in which Figure 1 is a side elevation of the device, partly in section and partly broken away to indicate where parts should preferably be lengthened to give the best results in operat ing the device.

Fig. 2 is a fragmentary detail side elevation of the upper termination of the tack selecting member, and the upper end or termination of the receiving tube.

Fig. 3 is a detail top plan view of the tack selecting member.

Fig. 4 is a detail front end elevation of the tack selecting member.

Fig. 5 is a fragmentary detail view partly in section of the operating and connecting bar and the upper jaw member.

The standard 6 is mounted on the base 7 for properly supporting the whole device. The foot pedal 8 is pivotally supported at 9, and has pivotal engagement at 10- with the operating bar 11. To allow properly guided movement of the foot treadle, a slot 12 is provided in the standard, and the ends of this slot serve to limit the vertical movement allowed to the foot treadle.

The foot pedal and the operating bar or rod 11 are automatically moved back to their inoperative positions and are normally held in their inoperative positions by a spring 13. This spring is disposed within the standard and surrounds the rod 11. The spring 13 is disposed between the inner terminations of screws 14 inserted in the standard and a pin 15 on the rod 11 so that a downward movement of the foot pedal with the rod 11 will produce a compression of the spring 15. The expansion of the spring 13 when, released, causes the return of the foot pedal and the rod 11. The spring may, of course, be engaged by various other similar means between the standard and the rod without materially departing from the principle of the invention.

The relative movement between the two jaw members 16 and 17 is controlled by the foot pedal on the standard. The upper termination of the rod 11 is in operative connection with the jaw member 17. For certain reasons that will be set forth hereafter, the rod 11 must continue to move after the jaw 17 has reached its lowermost position. For this difference in the movements between the rod and the jaw member 17, the telescopic engagement, illustrated in detail in Fig. 5, is preferred, where the spring 18 has one of its ends in engagement with the lower end of the arm 17 at 19 and its opposite end in engagement with a pin 20 on the rod 11.

On a downward movement of the foot pedal 8, the rod 11 and the arm or jaw member 17 move in the same direction. As soon as the jaw end 21 of the member 17 comes into engagement with the jaw end 22 of the member 16, the movement of the member 17 comes to a stop while the rod continues to move downwardly thereby compressing the spring 18 within the member 17.,

The double lever 23, pivotally supported at 24, engages at 25 with the operating rod 11. On a downward movement of the foot pedal 8, the end engaging with the'rod 11 ismoved to the positionindicated at 26 in dotted lines. The other, end 27 of the double lever 23 is pivotally engaged to the nailing member 29, as indicated at 28. j

The downward movement of the rod 11, after the jaw member17 has engaged the jaw member 16, serves mainly to operate thenailing member after the jaw ends 21 and 22 have come into contact. In inoperative position, the nailing member 29 is withdrawn from the end of the arm 16 so as to bring the front end of the nailing member to a position indicated at 30. From this illustration it will be understood that the nailing member is quite a distance from the end 22 of the hollow jaw member 16 when the two jaw ends 21 and 22 become engaged, and that the continued downward movement of the operating rod 11 will op erate the nailing member 29 to drive a nail or tack from the hollow jaw member 16 against the end 21 of the jaw member 17.

A tack magazine 31 is provided for holding tacks ready to be used in this device. A

tube 32 forms the communication between A tack selector operating bar 35 is connected to the lever 23 and terminates within the'magazinexnear the end 3 l-of the tube 32. A selecting member 36 is pivotally mounted on the termination of the selector operating bar35'. The termination of the member 36 is notched or provided with an open forklike engaging and selecting-end- 40, so that a tack 37 may rest in the fork-like opening of the selecting member 36v so as to point into;- the tube 32 when the tack selector is in a position above the beveled termination of the tube 32. In descending, the .member 36 V pivoted at 39 on the end of the bar 35 tilts upwardly as soon as it strikes the tube 32 to the positionindicated in dotted lines at 38. f

The magazine is preferably kept fullof tacks to a point just below the openingof the tube, so that the vdescending selector must dip and sink into the mass of stored tacks thereby allowing tacksto come above the selecting 'member36. Any tacks located above the selector are pushed upwardly when the selector is moved upwardly. The cut-out 40 is, however, proportionedjso that only one t-ack'remainsin the cut-out l0 with-its point in the direction downwardly into the tube 32,

and all other tacks fall or and out oit'the'way "sogtha-t the one -selected tack may easily fallinto the tube when theselector descends the next time. The tube is'ma'de long enough, and the magazine is disposed high enough to causethe' selectedtackj to slide through the tube into the hollow jaw member in front-of thenailing member 29 ready to be' pushed upwardly by then'ext movement of the de' v1ce.
